NEW SPECTROSCOPIC TECHNIQUES FOR STUDYING THE ORIGIN OF MOLECULAR PHOSPHORESCENCE.
Abstract
New indirect techniques are discussed by which one can assign the zero-field level(s) from which the emission of vibronic bands in the spectrum originates. These methods are based on changing the relative populations of the zero-field levels and observing the corresponding changes in the relative intensity of the different vibronic bands at temperatures for which the electron spin-lattice relaxation processes between the zero-field levels are slower than or comparable to the radiative processes. These methods are applied to 2,3-dichloroquinoxaline. A summary of the interpretation of the results obtained and their correlation with theory is given in this paper, but the details of the work are not given. (Author)
